[. . . ] For the Skytitle animation, try skya001. tga--"sky" describes the animation, "a" is the version, and "001" allows the creation of sequential files from 1 to 999. You must always begin or end the filename with a number with sufficient zeroes to accommodate the length of your animation. All frames of the animation are automatically saved and numbered as sequential files. Saving your animation as sequential TARGA files has several advantages. The TARGA format is a common one used for video and is easily imported into video editing and compositing programs. The TARGA format will preserve alpha channel data, also making the images easier to composite. Corel Painter allows you to import sequentially numbered TARGA files into a new Corel Painter movie file. Academic Courseware: Chapter 5 Joyce Ryan 53 Academic Courseware: Chapter 5 Joyce Ryan 54 Chapter 6 Saving and Exporting Movies Once your movie is finished, you can save it or export it in various file formats. In this chapter, you will find out about the different saving and exporting options you have for your movie. Corel Painter provides several options for saving and exporting your finished movies. Some file formats (such as QuickTime and Video for Windows) have compression options available. Exporting a single image from a movie You can export a single frame from your movie as a separate image. Export a single image from a movie 1 Display the frame you want to export in the image window. You can click on the frame thumbnail in the Frame Stacks palette to display the frame. Select Save Current Frame As Image, and click OK. 3 In the Save Image As dialog box, choose a location and file format, enter a name for the file, and click Save. Exporting movies as QuickTime movies The word "codec" comes from combining the words "compression" and "decompression. " A codec is any technology for compressing and decompressing data. Codecs can be implemented in software, hardware, or a combination of both. Some popular codecs for computer video include MPEG, Indeo® and Cinepak®. You can export a movie as a QuickTime movie on either the Macintosh or the Windows platform. QuickTime supports different compression schemes (codecs). The following descriptions of the main compression options should help you choose one; however, you'll probably want to experiment with different compressors and settings to identify the best settings for your work. You may also have additional compression methods available depending on your hardware. Academic Courseware: Chapter 6 Joyce Ryan 55 The compression ratio is inversely proportional to image quality. The Quality slider allows you to set an optimum level between the amount of compression and image quality. For most work in Corel Painter, you'll want Quality set to High. Animation This compression method works well with areas of continuous tone. If you set Quality to Best and make every frame a key frame, this compressor is lossless. For most Corel Painter animations, this compressor is a good choice. Cinepak This method produces acceptable motion and image quality at remarkably small file sizes. [. . . ] Bitmap -- Also referred to as a "raster image, " a bitmap is an array (or grid) of pixels used to describe an image. Cel -- Traditionally, animation drawings were inked onto transparent sheets of celluloid or acetate called "cels. " The cel was turned over and painted on the back with special "cel vinyl" paints, resulting in flat colors and an intact ink line. Color Resolution -- Color resolution represents the ability to reproduce fine color detail, or fine gradations between colors. Academic Courseware: Joyce Ryan 97 DPI -- Dots per inch. The resolution of output devices (printers) is measured in DPI. [. . . ]
